COA and Quality Assurance
Spark Peptide provides a lot-specific Certificate of Analysis for every IGF-1 LR3 lot. Each COA documents identity by HPLC and/or mass spectrometry, purity, and, where applicable, sterility and endotoxin levels, plus lot-specific storage guidance. Testing is conducted by independent third-party laboratories including Janoshik. COAs are lot-traceable and available on the Lab Tests page.
Handling and Storage
Store unopened IGF-1 LR3 vials at 36-46°F (2-8°C) for routine laboratory storage or at 0°F (-18°C) or below for longer-term preservation. Keep vials tightly sealed and protected from light, heat, and moisture until needed for research. When preparing a working solution, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with validated laboratory procedures. Prepared solutions may be maintained under refrigerated or frozen conditions as required by the research protocol, with aliquoting commonly used to help preserve sample integrity by minimizing repeated freeze-thaw cycles. Always follow institutional biosafety, laboratory handling, and disposal requirements.
Legal and Regulatory Disclaimer
IGF-1 LR3 is supplied strictly for laboratory research use only. It is not approved for human or veterinary use, clinical administration, therapeutic applications, or diagnostic procedures of any kind. Its safety, efficacy, and appropriate handling in humans or animals have not been established. Purchasers are responsible for compliance with all applicable local, state, and federal laws and institutional biosafety regulations.
